1000+ Head-Fier
Update from my side with my Japanese DP-X1 unit:
Ordered on Nov 2015, shipped out Jan 2016 via PriceJapan.
I had initially thought it was just the angled 3.5mm trs Neutrik plug that came with my ciems that wasn't up to spec, since it would unplug itself by the tiniest of movement and cause play pause as it detected headphones plug removal automatically. I had posted about this issue with photo deep in this thread.
Well turns out it happened again with another angled 3.5mm TRS plug of another cable, this the big tankish oyaide one. But I had again dismissed it and pinned it against the angled type plug which more easily makes rotation movement due to the cable angle. Because when I was using the tiny straight stock Noble cable I didn't get any issue, and also with the small factor angled plug of the Fiio EX-1, it worked fine without any unwanted pausing...
Well now it's been the 3rd week.Now that I can't use the EX-1 with the DP-X1 because it now too unplug itself all the time and way to fast. Within seconds of putting it in a pocket I start to get small snappy tick sounds while music plays because of connection movement and within a moment later the doomed auto pause because it unplugged itself 1mm which is enough for the player to detect it causing headphone disconnection...
My dilemma now is that I only have the 2.5mms TRRS jack that works flawlessly -for the time being- with the Eidolic straight spacious barrel which sits flush against the DP-X1 and doesn't move and is gripped nicely inside.
My fear is that I'll start to get the same issue with my balanced output sooner or later. And even if it never happens I basically have a devalued unit as I can't expect to resell it in the future if the main 3.5mm TRS output is not working well.
I'm inclined to ship it back on my expense to pricejapan while I still have 5 months of local warranty. Trouble is, I don't know if Kaneda-San recovered or not.
This really sucks.
The internal plastic housing in your 3.5 mm has very likely warped, or broke. This is causing contact issues with any 3.5 mm TRS jacks.
Essentially, the 3.5 mm output is not capable or fit to use with any 3.5 mm jack, because some jacks will have minuet differences (ie your DP-X1 has strict tolerances and is inflexible to even slightly thicker TRS barrels).
To make matters worse, the issue with broken jacks was mostly with 2.5 mm outputs, meaning your unit, part of the original batch, may also also develop the same issue.
What I'm about to say next will upset you.
I have information from Kaneda of PriceJapan.com that they will NOT replace broken jack issues, and will ONLY REPAIR THEMSELVES such units instead.
They will work on a case-by-case basis but that is the stance PriceJapan.com have taken.
I cannot divulge how or why I have this info (with email proof), but it lead to my contact with Onkyo UK and the info I've posted already.
I am really sorry dude, but contact Kaneda anyway, see what he says.
